Training project for React. You have a counter, clicking on the plus or minus sign increments or decrements the counter (min 0 and max 10). There's also a "Add counter" button which creates another counter, you can have up to three counters. Each counter works independently.
Main difficulty : I'm only using one state to manage everything.
- states hook on an array
- ternary conditions
- mapping
- event handler (onClick)
